Item Description, From the Manufacturer:

The Only Aftermarket Polaris Differential

Once again, SuperATV brings you a product you can’t get anywhere else. SuperATV’s Polaris Complete Differential is the only aftermarket Polaris diff on the market. You’re probably here because you blew your stock diff and you may be wondering, “why not just reorder the OEM diff?” The answer is simple—if your stock differential failed, do you really want to go back to it? SuperATV’s Complete Front Differential gives you the same performance you love on your stock machine with the built for battle strength you expect from SuperATV. It’s designed to deliver power to your front wheels and lock when you want it to. It’s a replacement front differential and a major upgrade—that way you can keep riding hard

Why SuperATV’s Differential is Better

You don’t just get replacement internals for your diff—we give you the complete differential all assembled and ready to install. You get a whole new heavy-duty cast or billet aluminum case, thicker gears, bushings, seals, hubs, Sprague, armature, and wiring. To take our differential to the next level, we use 7075-T6 aircraft grade aluminum for our Sprague carrier to give maximum strength and durability. That means our differential can endure ride after ride of hard differential lock engagements without failing—which also means, you won’t have to worry about getting a replacement anytime soon. We have drastically improved the components prone to failure and wrapped them in a stronger case.

Stronger Mounting

We’ve beefed up our differential case by using helical inserts in the mounting threads and by adding additional material to the mounting locations. These inserts make it virtually impossible for the mounting bolts to wallow out or pull out over time. The additional material gives our diff a much more secure mount. The OEM diff has feet-like mounting locations, while ours mounts to a single block built into the body of the diff. We also thickened the pinion gear tube to make sure it can stand up to every bump, jar, and torque load. Plus, we make it easy on you. We use a bolt-on cap to retain the pinion bearing instead of a snap ring. That means you can service your pinion gear without destroying your seal.

Billet Case

Billet is denser, stronger, and less porous than cast, plus it looks really stinking good. It keeps everything together without flexing under load to ensure your gears, hubs, and sprague are all running smoothly.

Install with Confidence

What does all the extra strength mean for you? You can ride hard and go deep. You can haul more and hit more. Keep your four-wheel drive engaged and gun it—this diff is designed for abuse. Don’t go back to stock—for less than an OEM differential you get a stronger, preassembled, bolt-on ready differential that doesn’t quit. What’s not to love?
